Prophait builds integrated master schedules in your browser — a modern-day CPM engine, an Excel-grade grid, and Claude built in as an assistant that speaks fluent scheduler.
Why Prophait
Project trackers can't compute a critical path. Legacy desktop tools can't share a link. Prophait does both jobs — without compromise on either.
CPM — the critical path method — is the math that makes a schedule defensible. Prophait runs the full forward and backward pass on every edit: links with lag, constraints, calendars, and float, with the critical path lit up in red across the grid and Gantt — and an inspector for programs that have more than one.
"Add a 5-day design task after SRR and show me the critical path." The assistant reads and edits your schedule with real operations — every change undoable and audited.
DCMA 14-point health checks, earned value (CPI/SPI) live on every schedule, named baseline archive, and a full audit trail. Program-review-ready without exporting a thing.
Link a schedule to a Jira project, create issues straight from tasks, and pull status back into % complete — the IMS and the engineering tracker finally agree.
Claude, built in
Prophait's assistant is powered by Claude, Anthropic's frontier model — and it works with the same operations you do: adding tasks, linking logic, running analysis. Nothing it does is a black box, every change is undoable, and it bills your own Anthropic key, so your schedule data never trains or funds anyone else's model.
Everything a planner expects
Keyboard-first grid: type to edit, arrow keys, copy and paste straight to Excel, filter any column, freeze panes, group by slack or resource. Smooth at 2,000+ tasks.
Import MS Project XML and Primavera P6 XER with hierarchy, logic, resources, constraints, and progress intact — warnings, not failures, for anything that doesn't map.
Every company is a separate tenant enforced at the database layer, not just the app. Invite-only team joining, checkout discipline against conflicting edits, and every change audited.
Bring your own Anthropic API key. AI usage bills your account at cost — we never mark it up, store your key in plaintext, or see your prompts as a business model.
Capture named baselines before every review, compare live dates against the frozen plan, and re-apply an archived baseline when the replan gets walked back.
See per-day demand against capacity on a histogram under the Gantt, and resolve over-allocation with one click of delay-based leveling — pinned tasks respected.
Create Jira issues straight from tasks, push names, notes, and due dates, and pull status back into % complete — deterministic, on-demand sync with org credentials stored encrypted.
Every workspace ships with a full CubeSat development program and a MIL-STD-881-style WBS — copy one and start planning instead of staring at an empty grid.
Pop the grid, the Gantt, or the assistant into its own browser window — every pane stays live and in sync, the way a scheduler's desk actually works.
Hand customers and reviewers a live, read-only view of the schedule — no account, no export. Links expire after seven days and can be revoked the moment a review ends.

Dedicated-database or on-premise isolation for ITAR-sensitive programs, enterprise SSO, security review support, and an SLA.
Security
Schedule data is competitive data — and sometimes controlled data. Prophait treats it that way at every layer.
Every company is a separate tenant enforced with Postgres row-level security — a second, independent wall beneath the application layer.
API keys and integration tokens are stored encrypted and write-only — even admins only ever see a masked hint.
Task edits, AI actions, membership changes, baseline captures — who, what, and when, in an append-only trail your org admins can review.
TLS everywhere, role-based permissions, invite-only team joining, and checkout discipline so two planners never trample one schedule.
